I think so, entertaining themselves. Happens a lot. That's why I only give nearest tube, no postcode or street. What info do you give them?
Usually it's 'something came up at work', or whatever, but yes a lot just plain cancell the second the phone's clicks off.
Also they might book a handful of girls as a safety net and only decide on their favourite once they've confirmed who's available.
I think they're clever and cancel so they don't get blacklisted when they genuinely need a service. Some punters know we share information.Before I wouldn't bother to log them but now I tag as waster and block, even the 'meeting's been rearranged' ones.That's popular too.
I text them back 'do not contact me' again so they know this bridge is burnt. One strike rule.
